The key aspect of audio level adjustment in AV systems is to create an optimal "gain structure." This concept refers to managing the levels of audio signals through the various components of an AV system to ensure that they all work together effectively. Proper gain structure is essential for maintaining audio quality by preventing distortion, noise, and signal degradation, which can occur when levels are too high or too low.

An optimal gain structure ensures each stage of the audio signal processing - from the microphone to the amplifiers and speakers - operates within its ideal range. This not only enhances the clarity and dynamic range of the audio but also helps avoid issues such as clipping, where the audio signal exceeds the capacity of the equipment, resulting in a distorted output.

Other options do not address the fundamental goal of audio level adjustment as effectively. While ensuring that all devices are identical might seem beneficial, it does not address the specific interplay of audio levels. Amplifying only background music might be relevant in a particular context, but it does not encompass the broader principles of gain structure and overall system performance. Changing device settings frequently could lead to inconsistency and instability in audio quality, which is counterproductive to achieving a well-balanced sound.
